RE: [syslog-ng] I/O error occurred while reading; fd='4',error='Operation not permitted (1)'

fd 4 is /proc/kmsg ... Try changing the path to "/var/local/chroot/syslogng/proc/kmsg"

Done. I changed my "source" directive in my conf file to include: file("/var/local/chroot/syslogng/proc/kmsg" log_prefix("kernel: ")); but I'm still getting the same problem on startup.
